E80 connected to a DSM300, can't update

[Chuck - Raymarine - Moderator]

Jose,

As E-Series Classic MFDs are not designed to auto-sense, compatible devices featuring an Ethernet communications interface (ex. other E-Series Classic MFDs, DSM30/300/CP300/CP370, SR100, etc.) must be interfaced the MFD via an assembly constructed from a pair of Raymarine Ethernet Cables (in this case SeaTalkhs (M) to SeaTalkhs (M) Cables) which have been joined to one another via a SeaTalkhs Crossover Coupler or SeaTalkhs Network Switch. Key is this interface is that the plug of the cable connected to the MFD's Ethernet socket and to the DSM30/300's socket feature a SeaTalkhs (M) plug.

Again, should you be unable to update the DSM's software using the procedure attached to the prior response, then it is recommended that the DSM be sent to Raymarine’s Product Repair Center to have its software update as well as to be bench checked.
